CAR-ROOF.

Specification of Letters Patent.

Patented July 15, 1919.

Application filed May 11, 1917. Serial No. 158,367.

To all whom it may concern:

Be it known that I, GEORGE W. RrsTINE, Jr., a citizen of the UnitedStates, residing in Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in CarRoofs,of which the following is a specification.

This invention relates to an improvement in car roof construction, anobject being to provide a roof having a maximum of strength with aminimum weight and which will be simple'in construction and capable ofbeing manufactured at low cost.

Another object of the invention is to provide an improved carline whichcan be made of a commercial section or pressed shape, to which the roofplates are adapted to be attached by resilient means and without the useof rivets passing through the roof plates.

Another object of the invention is to provide simple means for theattachment of the roof plates to the carline, which, while formingWeatherproof joints between the roof plates and carline, will permit ofthe easy removal and replacement, when necessary, of such plates.

Another object of the invention is to provide means for attaching theroof plates to the carline in such a manner that such means is soanchored to the side plates, that u large proportion of the strain dueto holding the roof plates in contact with the carline is transmitted tothe side plates.

Referring now to the drawings in which like reference character refer tolike parts, Figure l is a plan view of a portion of a car roof embodyingthe invention; Fig?. is a sectional View of the same taken on the line2-2 of Fig. 1 and Fig. 3 is an end elevation of the same. Fig. 4 is anenlarged sectional view taken on the line 4-4 of Fig. 1, and F ig. 5 isa cross sectional view taken on the line 5-5 of Fig. 1; Figs. 6 and 7are sectional views of a modification of the invention, which viewscorrespond to Figs. l and 5 of the preferred form.

Referring now in detail to the drawings, 1 indicates one of the sideplates of the car which may be of any suitable form or construction, butas shown in the drawings are preferably of angular cross section. 2indicates one of the carlines which extend across the car and aresecured to the side plates 1. These carlines may be of any suitable formbut are preferably of rolled or pressed channel form having ahorizontally disposed web 3 and vertical flanges 4 which extend upwardlytherefrom.

The roof comprises a plurality of plates 5, 5, which rest on the flanges4 of the carlines and preferably extend continuously' across the fullWidth of the car. Each of these roof plates is provided with downturnedend and side flanges 6 and 7 respectively, the end flanges 6 overlappingthe side plates when the roof plate is in its propel' position on thecarline 2, and the side flanges 7 extending into adjacent carlines. Theside flanges 7 are provided with perforations S at intervals throughouttheir lengths which are adapted to receive members 9 for fastening theroof plates to the carlines. The members 9 are located within thecarlines and between the side flanges t of the roof plates, and areslightly bowed or curved, the side portions l() of the members passingthrough the perforations 8 of adjacent roof plates. The lower portionsof the side flanges 7 of the roof plates are doubled upon themselves, soas to provide additional thickness of metal and strength in that portionof the flange which is slotted for the ends 10 of the members 9 to passthrough.

llindicates bolts which extend from side to side of the car and areanchored in bracket members 12 which are secured to the side plates 1 atthe ends of the carline. Between the bracket members 12 these bolts seatin grooves or recesses 13 formed in the upper surface of the members 9,and when the nuts 14 at the ends of the bolts are tightened against thebracket members 12, the tension on the bolts tending to straighten them,roduoes a downward pressure on the mem ers 9, which engage the sideflanges 7 of the roof plates, thus holding the roof plates to thecarlines. The curved form of the carline, curving downwardly to eachside of the can insures that water falling in the channel of the carlinewill be conducted to one or both ends thereof, and permitted to escapethrough slots or notches 17, 17, which are out in the end flanges of theroof plates.

In the modification of the invention as shown in Figs. 6 and 7 thetransverse bolts l1 of the preferred form are omitted, and the carlineis provided with a plurality of shoulder bolts l5 which are secured inthe web of the carline and are adapted to extend through the members 9,the upper ends of these bolts being provided with a threaded portionadapted to receive a nut 16, which nut when ti htened produces adownward pressure on t e members 9, which engage the side flanges T ofthe roof plates, thus holding the roof plates to the rarline.

It is to be understood that the members 9 may if desired be made ofmaterial having more or less resiliency, thus roviding for a greateramount of movement between adjacent roof plates, and a greater amount ofmovement. between the roof plates and the carlines which support them.

It will be noted from the foregoing description that the root plates areheld to the upper jtrame work oi' the ear without rivets, and also thatthey are held in suoli a manner as to permit slight movement between theplates as the oar weaves due to uneven track and other servireconditions.

Aalthough in the drawings and foregoing descrip-tion only portions ofone carline and the roof plates. and the several parts ooperatingtherewith are illustrated and described, it will be understood by thoseskilled in the art. that both ends of the oarline are substantiallyalike` and that a railway ear roof is composed ot a plurality of suoliparts.

Claims:

1. ln a oar roof, a oarline, root1 plates supported by said rai-line andhaving openings formed therein, members engaging said openings, saidmembers having grooves in their upper surfaces and means engaging saidgrooves to retain the roof plates on said earline, and means forapplying tension to said means.

2. In a car roof, a carline, rooplates snpported by said earline andhaving openings formed therein. resilient members engaging saidopenings, said members having grooves formed in their upper surfaces,and means engaging said grooves to retain the roof plates on` saidearline, and means for applying tension to said means.

Copies of this patent may be obtained for 3. ln a ear roof, a oarline,roof plates supported by said oarline and having openings formedtherein, members engaging said openings, said members having groovesformed in their upper surfaces and a rod extending from side to side ofthe roof, adapted to engage the grooves in said members and retain theroof plates on said earline, and means for a plying tension to said rod.

i. lh a car roof, side plates, a earline, roof plates supported by saidcarline and having openings formed therein, members engaging saidopenings, said members having grooves and a rod extending from side toside of the roof, adapted to engage the grooves in said members andretain the roof plates on said cai-line. said rod being secured to saidside plates, and means at the sides of the roof for applying tension tosaid rod.

ln a car roof, a oarline of flanged seotion, roof plates supported bythe flanges of said oarline, lianges on said roof plates eX- tendingbetween the flanges of said earline and having openings formed therein,members engaging said openings, said members having grooves formedtherein and rod means engaging said grooves to retain the roof plates onsaid oarline., and means for applying tension to said rod means.

G. In a oar roof, a oarline, roof plates supported by said earline,flanges on said roof plates and having vportions folded upon themselvesand openings formed in said folded portions, members engaging saidopenings, said members having V.grooves formed in their upper surfacesand means engag' said grooves to retain the roof plates to sai carline,and means for applying tension to said means.

In testimony whereof I atlix my signature in the presence of twoWitnesses.
